This application claims the priority of Chinese patent application No.201910730188.8, filed on Aug. 8, 2019, which is incorporated herewith byreference.

BACKGROUND OF THE INVENTION 1. Field of the Invention

The invention relates to a building block, in particular to a buildingblock having a light-emitting element disposed therein. The lightemitted from the light-emitting element can pass through the main bodyof the building block and make the building block have a light-emittingeffect.

2. The Prior Arts

The conventional jigsaw puzzles use a plurality of small interlockingunits to form a complete pattern. In particular, each of interlockingunits has a unique shape such that each side of the interlocking unitscan only be connected with another specific interlocking unit. Thereby,the user can gradually connect the interlocking units with each other toproduce a large complex pattern by trial and error. However, althoughthe interconnection of the interlocking units of the jigsaw puzzles isadvantageous for the user to connect to form a complex pattern, it alsolimits the possibility for the user to use the interlocking units toform different patterns. The conventional jigsaw puzzles can only form asingle pattern, which lacks variability in use.

In addition, some manufacturers have developed a light-emitting buildingblock assembly. The light-emitting building blocks in the light-emittingbuilding block assembly can be assembled and connected in many ways toconstruct objects having light and shadow effects, and thelight-emitting building block assembly allows for the construction of avariety of different shapes and models by changing the interconnectionrelationship between the light-emitting building blocks. However, thelight and shadow effect of the convention light-emitting building blockscannot form letters or patterns. Thus, the functions of thelight-emitting building blocks are not perfect.

Therefore, the jigsaw puzzles and light-emitting building blocksavailable on the market still need to be improved to solve the existingproblems.

That is, the circuit board 20 is received in the building blockboard 10, but the configuration is not limited thereto.

The light-emitting elements 30 are disposed on a top surface of thecircuit board 20 facing the building block board 10. According to thefirst embodiment, the positions of the light-emitting elements 30 arethe same as the positions of the connection portions 12. That is, thepositions of the light-emitting elements 30 overlap with the positionsof the connection portions 12 when viewed from the top surface 111 ofthe building block board 10. The light emitted from each of thelight-emitting elements 30 passes through the building block board 10via the corresponding connection portions 12, but the positions of thelight-emitting elements 30 and the positions of the connection portions12 are not limited to the same locations. The positions of thelight-emitting elements 30 can also correspond to the positions of theconnection portions 12 in other ways, as long as the light emitted fromthe light-emitting elements 30 can pass through the building block board10 via the connection portion 12. The light-emitting elements 30 areelectrically connected with each other.

The building block board 10 according to the first embodiment is madeof, but not limited to, a light-transmitting material such that thelight emitted from the light-emitting elements 30 can pass through thebuilding block board 10 via the connection portions 12. In the followingdescription, the present invention further provides two embodiments inwhich the light emitted from the light-emitting elements 30 can alsopass through the building block board 10 via the connection portions 12.

Referring to FIG. 4, the building block board 10A according to a secondembodiment of the present invention is made of an opaque material, andeach connection portion 12A is provided with a light guide hole 121Apassing therethrough. When the building block board 10A is not engagedwith any of the light-shielding building bricks 40A, the illumination ofthe building block board 10A is the multi-point illumination from theconnection portions 12A instead of the full-surface illumination fromthe whole building block board 10A according to the first embodiment.

Referring to FIG. 5, the plate body 11B of the building block board 10Baccording to a third embodiment of the present invention is made of anopaque material. The plate body 11B includes a plurality of throughholes 113B, and the through holes 113B extend to the top surface 111Band the bottom surface 112B of the plate body 11B. The connectionportions 12B made of a light-transmitting material are respectivelyreceived in the through holes 113B such that the way of illumination canbe the same as that of the second embodiment. According to the thirdembodiment, an end of the connection portion 12B facing the circuitboard 20B is aligned with, but not limited to, the bottom surface 112Bof the building block board 10B. The end of connection portion 12Bfacing the circuit board 20B may also protrude out of or retract insideof the bottom surface 112B of the building block board 10B.

Referring back to FIG. 1 to FIG. 3, the light-shielding building brick40 according to the first embodiment of the present invention can befitted with the connection portion 12 of the building block board 10.Specifically, one side of the light-shielding building brick 40 isformed with a first fitting portion 41 as shown in FIG. 3, and the firstfitting portion 41 can be fitted with the connection portion 12 of thebuilding block board 10. When the light-shielding building brick 40 isfitted with one of the connection portions 12 of the building blockboard 10, the light-shielding building brick 40 shields the connectionportion 12. That is, when the light-shielding building brick 40 isfitted with and mounted on the connection portion 12, thelight-shielding building brick 40 blocks the light emitted from thelight-emitting element 30 from passing through the connection portion12, thereby making the light emitted from the light-emitting element 30produce a light-and-dark difference on the top surface 111 of thebuilding block board 10. When a plurality of light-shielding buildingbricks 40 are fitted with and mounted on appropriate positions of thebuilding block board 10, the light-shielding building bricks 40 can bearranged to form letters or patterns. Then, the light emitted from thelight-emitting elements 30 can form the light-and-dark difference on thetop surface 111 of the building block board 10, and form the letters orpatterns by the light-and-dark difference.

The light-transmitting building brick 50 can be fitted with theconnection portion 12 of the building block board 10. Specifically, oneside of the light-transmitting building brick 50 is formed with a secondfitting portion 51 as shown in FIG. 3, and the second fitting portion 51can be fitted with the connection portion 12 of the building block board10. Furthermore, the shape of the second fitting portion 51 is the sameas the shape of the connection portion 12 of the light-shieldingbuilding bricks 40. Each of the light-transmitting building bricks 50can be made of a material with a single color. Moreover, thelight-transmitting building bricks 50 according to another preferredembodiment may have at least two different colors. Thereby, the patternformed by puzzle building block according to the present invention canfurther provide color differences in addition to the light-and-darkdifference by using the light-transmitting building bricks 50 havingdifferent colors. Further, each of the light-emitting elements 30according to the present invention can also be a color light-emittingelement 30. The light-emitting element 30 can respectively emit light ofdifferent colors, such that the respective connection portions 12 on thebuilding block board 10 can exhibit various light and shadow effects bythe color differences of the respective light-emitting elements 30.

According to the present embodiment, the sum of the number of thelight-transmitting building bricks 50 and the number of thelight-shielding building bricks 40 are equal to the number of theconnection portions 12. That is, the connection portions 12 are arrangedin a matrix and distributed all over the top surface 111 of the buildingblock board 10. The light-shielding building bricks 40 are mounted onpart of the connection portions 12 on the building block board 10 toform the letters or patterns, and the light-transmitting building brick50 is mounted on the connection portions 12 on which the light-shieldingbuilding bricks 40 are not mounted.

According to the present embodiment, the connection portions 12 arecylinders protruded from the top surface of the building block board 10,and the first fitting portions 41 and the second fitting portions 51 arecircular recesses defined in the building bricks. The shapes of theconnection portions and the fitting portions are not limited to thecylinder and the circular recesses, as long as the connection portions12 can be fitted with the first fitting portion 41 and the secondfitting portion 51. For example, the connection portion 12 may be asquare recess defined in the building block board 10, the first fittingportion 41 and the second fitting portion 51 are square columns, and thefirst fitting portion 41 and the second fitting portion 51 may be fittedwith the connection portion 12.

Referring to FIG. 6, the puzzle building block capable of changinglight-emitting areas according to a fourth embodiment of the presentinvention is substantially the same as the one according to the firstembodiment. The difference between the fourth embodiment and the firstembodiment is in that the fourth embodiment does not have anylight-transmitting building brick but only has the light-shieldingbuilding bricks 40C, thereby arranging to form letters or patterns.According to the present embodiment, part of the connection portions 12Care not fitted with the light-shielding building bricks 40C, and thelight emitted from the light-emitting elements 30C can pass throughthese connection portions 12C. The connection portions 12C without beingfitted with the light-shielding building bricks 40C and connectionportions 12C fitted with the light-shielding building bricks 40C thenform patterns by creating a light-and-dark difference, but not limitedthereto. According to another preferred embodiment of the presentinvention, the light-shielding building bricks 40C may be replaced bythe light-transmitting building bricks, and a color of thelight-transmitting building brick is different from that of thelight-emitting element 30C. After the connection portion 12C is fittedwith the light-transmitting building brick, the connection portion 12Cis covered by the light-transmitting building brick. The color of thelight emitted from the light-emitting element 30C changes after passingthrough the connection portion 12C and the light-transmitting buildingbrick covering the connection portion 12C. Therefore, the light emittedfrom the light-emitting element 30C have color differences on the topsurface 111C of the building block board 10C, and letters or patternsare formed by the color differences.

Referring to FIG. 7, the puzzle building block capable of changinglight-emitting areas according to a fifth embodiment of the presentinvention is substantially the same as the one according to the firstembodiment. The difference between the fifth embodiment and the firstembodiment is in that the connection portions 12D of the building blockboard 10D are arranged on the top surface 111D of the building blockboard 10D to form letters or patterns. Furthermore, according to thefifth embodiment, there is no light-shielding building brick, but thereare only the light-transmitting building bricks 50D. The number of thelight-transmitting building bricks 50D is the same as the number of theconnection portions 12D. That is, all of the connection portions 12D canbe fitted with the light-transmitting building bricks 50D. When thepuzzle building block according to the fifth embodiment is in use, thelight-transmitting building bricks 50D are respectively fitted with theconnection portions 12D such that the shapes of the letters or patternsformed by the arranged light-transmitting building bricks 50D areexactly the same as those of the letters or patterns formed by theconnection portions 12D. However, the color of the letters or patternsare converted from the color of the light-emitting elements 30D to thecolor of the light-transmitting building bricks 50D. The user can easilymount the light-transmitting building bricks 50D onto the building blockboard 10D one by one and the light-transmitting building bricks 50D canautomatically form the letters or patterns, which is more convenient touse, but not limited thereto. The present embodiment can also have thefollowing variations:

First, the light-emitting element 30D may be a color light-emittingelement, such as a three-color LED, and therefore the colorlight-emitting element 30D can directly make the respective connectionportions 12D display in different colors. Thus, the letters or patternspresented according to the present embodiment can have colordifferences, and show various light and shadow effects, such as contoursor shadows.

Secondly, each of the light-transmitting building bricks 50D are made ofa material with a single color and have at least two different colors,thereby further enhancing the color differences for the letters orpatterns formed by the arranged light-transmitting building bricks 50Dand showing various light and shadow effects, such as contours orshadows.

Thirdly, it may further include a light-shielding building brick, andthe light-shielding building brick can be fitted with the connectionportions 12D. The number of the light-shielding building bricks fittedwith the connection portions 12D is less than the number of theconnection portions 12D. Therefore, part of the connection portions 12Dcan be shielded by the light-shielding building bricks. Then, theremaining unshielded connection portions 12D form new letters orpatterns, and the new letters or patterns are different from thoseformed by all of the connection portions 12D. For example, according toan embodiment, all of the connection portions 12D are arranged in theArabic numeral “8”. After part of the connection portions 12D are fittedwith the light-shielding building bricks, the unshielded connectionportions show the Arabic numeral “0”. Then, the light-transmittingbuilding bricks 50D may further be fitted with the unshielded connectionportions 12D such that the light-transmitting building bricks 50D showthe aforementioned Arabic numeral “0”. Because part of the light emittedfrom the light-emitting elements 30D is blocked by the light-shieldingbuilding bricks, a light-and-dark difference is generated on the topsurface 111D of the building block board 10D to form the letters orpatterns

Fourthly, there may be only a light-shielding building bricks butwithout any light-transmitting building brick 50D. The light-shieldingbuilding bricks are fitted with part of the connection portions 12D toprovide the shielding such that the remaining unshielded connectionportions 12D form new letters or patterns. The specific method is thesame as the one described in the foregoing description and will not berepeatedly described here.

Fifthly, regarding how the light emitted from the light-emittingelements 30D passing through the building block board 10D, it may alsohave variations as the second or third embodiment described above. Thatis, the light emitted from the light-emitting elements 30D passesthrough the light guide holes of the connection portions 12D as thesecond embodiment, or the light emitted from the light-emitting elements30D passes through the connection portions 12D made of thelight-transmitting material as the third embodiment. The specificimplementations have been described in the foregoing second and thirdembodiments, and will not be repeatedly described here.

Then, the user can fit the light-shielding building bricks 40 andthe light-transmitting building bricks 50 with the connection portions12 on the building block board 10 so that the light-shielding buildingbricks 40 are arranged to form the letters or patterns. The puzzlebuilding block capable of changing light-emitting areas according toother embodiments of the present invention can use thelight-transmitting building bricks 50 and/or the light-shielded buildingbricks 40 to form the letters or patterns as appropriate.

Referring to FIG. 8, a puzzle building block assembly according to thepresent invention includes a plurality of puzzle building blocks capableof changing light-emitting areas according to the first embodiment ofthe present invention, but not limited thereto.

Therefore, the puzzle buildingblock assembly can provide the patterns or letters in more detail.

The circuit boards 20 of the puzzle building blocks capable of changinglight-emitting areas of the puzzle building block assembly areelectrically connected with each other. Therefore, when the puzzlebuilding block assembly is in use, it only needs to connect one of thecircuit boards 20 among the puzzle building blocks capable of changinglight-emitting areas with the power source. Then, all of thelight-emitting elements 30 of the puzzle building blocks capable ofchanging light-emitting areas can be powered to illuminate. The puzzlebuilding block assembly according to the present embodiment includes aplurality of conductive cylinders 60 disposed between the circuit boards20 of the puzzle building blocks capable of changing light-emittingareas. The conductive cylinders 60, but not limited thereto,electrically connect the circuit boards 20 of the puzzle building blocksto each other.
